Abstract
"EQUILìBRIO DA TAXA DE TREPIDAçãO DO TUBO DE FLUXO E DE UMA BARRA DE EQUILìBRIO EM UM MEDIDOR DE FLUXO CORIOLIS DE TUBO RETO" Trata-se de um medidor de fluxo Coriolis possuindo um tubo de fluxo reto único, uma barra de equilíbrio paralela ao dito tubo de fluxo, uma barra de suporte conectando as extremidades da barra de equilíbrio com o tubo de fluxo e com uma caixa circunjacente. O equilíbrio dinâmico aperfeiçoado do medidor de fluxo é mantido em reposta às alterações na densidade do material fluindo por reduzir a função de trepidação da barra de equilíbrio e/ou do tubo de fluxo. Isto concentra a função de trepidação do medidor de fluxo na estrutura da barra de suporte. Um nó vibracional na estrutura de barra de suporte separa a função de trepidação efetiva da barra de equilíbrio da função de trepidação efetiva do tubo de fluxo. O nós vibracional move-se entro da barra de suporte em resposta à materiais com densidades diferentes no tubo de fluxo em tempos diferentes. Este movimento nodal altera a relação da função de trepidação da barra de equilíbrio efetiva com esta da função de trepidação efetiva do tubo de fluxo para manter o equilíbrio vibracional dinâmico aperfeiçoado do medidor de fluxo sem envolver a massa da caixa.
